    Problem with mp4 export

      I posted this as a reply to another discussion but have had no response so thought I should try it as a new thread.


      I have a single non-nested 10 minute sequence. I use  a slightly modified AME HDTV 1080p 25 HQ preset to export to H.264 mp4  as follows:


      PAL, 1920x1080, 25fps, progressive, VBR, 1  pass, Target 10Mbps, Max 25Mbps, AAC 160kbps, 48kHz.

      I dropped the  target bitrate from 35Mbps in the preset thinking that might be the  problem, but it didn't make a difference.


      The export  seems to go fine ie without errors, but playing back the exported mp4  gives the occasional but noticeable stutter using VLC or WMP, where the video pauses for a short while but the audio continues.


      I will be projecting the video on a large screen so need the best quality.


      I am using PPro 5.0.3 on an Intel i7 920, 12GB RAM, 4 x 1TB 7200 HDD, ATI Radeo 4870 1GB, Windows 7 Ultimate SP1.


      Any suggestions?
